CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 296,517, dated April 8, 1884. Application filed January 16,1884, (llo model.)

To @ZZ whom it may concern,.-

Be it known that I, BUssnLL BREWER, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Car-Axle Boxes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had .to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a vertical longitudinal section, illustrating this invention. Fig. 2 is a vertical transverse section.

This invention has relation to car axle boxes; and it consists in providing an interior oscillating bearing which will automatically adapt itself to the axle journal, whatever may be the relative position of said j ournal and of the axle-box Within which said bearing is located.

Phe invention also consists in combining with such interior oscillating bearings and the axle-journals anti-friction rollers.

The invention further consists in 'the construction and novel arrangement of the double roller, and the convex oscillating bearing, op erating in connection With said double roller, and a plane bearing in the upper part ofthe box; and the invention finally consists in providing, in connection with anti-friction rollers, elevator-lubricating devices adapted to raise the lubricating material in a posit-ive manner, all as hereinafter setforth.

In the accompanying drawings, theletter A designates the axle-box, which may be made in the usual manner, except that it is provided in its upper portion with achilled bearing, B, which is usually made plane. In front and rear of this bearing lugs c are located, and are perforated to receive the ends of a pin, d. The chilled bearing B is centrally7 arranged in the top of the box, and is usually made entire therewith, as shown in the drawings.

D represents the journal end of a car-axle extending into the box. In front and in rear of this journal are located lubricating-rollers E and l1, which operate in connection with rollers G and II, below them, the rollers Gand H being partially or wholly submerged in the lubricating material in the bottom chamber, K, of the box. y

L represents a double roller having the tvro roller-bearings m m, connected by a central cylinder or shaft, n. The roller-bearings and shaft of this double roller are. chilled.

S indicates the oscillating bearing,\vhicli is usually made with a chilled convex upper surface, p, which is designed to bear against the plane bearing B in the top of 'the box. The lower bearing-surface, t, of this oscillating piece is also chilled, and is designed to bear against the chilled shaft or connecting-cylinder n of the double roller. The oscillating bearing S is connected to the lugs c by the pin d, which serves to keep the bearing S 'in position, While allowing a free movement of oscillation. In this construction the Weight of the lcar on the box is transferred to the axle-journal through the top bearing, B, interior oscillating piece, S, and the double roller; and it is apparent that, Whatever be the relative positions of the axle journal and box, the oscillating bearing will automatically accommodate itself thereto in such a manner that. the roller-bearings of the double roller will at all times fully engage the axle-journal.

In some instances it may be desirable toY make the top bearing, I3, concave circularly, so that it will have more bearing-surface upon the oscillating piece S. In this case the pm d should Work in slots of sufficient size to allow a free movement of the oscillating bearing,

While controlling it against endwise thrust, and inother particulars the construction may be varied by those skilled in the art without departing from my invention.

It is obvious that the journal-box herein described is adapted for use upon passengercars, freight-cars, locomotives, and all shaftbearings to which it can be applied.
